From publisher blurb:
WHERE ARE OUR GODS NOW?
Dark Fantasy Religion is a collection of tables and short essays to inspire the creation of fantastic religions, taboos, deities, churches, etc . You can also use this book to generate characters, spirits and beliefs for stories, comic books, etc.
The focus is on dark fantasy tropes: flawed heroes, terrible villains, corrupting magic, ominous ruins and damned wastelands.
This is mostly a system-less book, to be used with any game of your choice, but some parts are written with the most popular RPGs in mind (you know, six abilities, hit points, saving throws, etc). It is especially suited for medieval dark fantasy games, such as my own (Dark Fantasy Basic).
It includes sections such as:
Religious characters: robes, holy symbols, hats... or revealing clothes.
Religious powers: baptize, convert, exorcize, excommunicate!
Taboos, oaths and vows: it's hard to be a follower!
Law, Chaos, and deities: a reflection about how deities fit in the cosmological order.
